IMPROVEMENT IN 'WlNDMlLL-MOTORS.

Specification forming part of Letters Patent No. 210,803, dated December 10, 1878; application filed November 9, 1878.

To all whom it may concern:

Be it known that I, ISAAC H. PALMER, of in the county of Columbia and State of Wisconsin, have invented a new and valuable Improvement in Windmill-Motors; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, malring a part of this specification, and to the letters of reference marked thereon.

Figure l of the drawings is a representation of a side view of my improved motor. Fig. 2 is a front view thereof, and Fig. 3 is a detail.

This invention has relation to improvements in mechanical powers designed especially to be actuated by a windengine.

The object of the invention is mainly to devise means in a reliable and economical manner for overcoming the dead-centers in pumping, grinding, and hoisting machines, and in other mechanisms usually operated by windwheels.

The nature of the invention consists in the arrangement and novel construction, in connection with a winding drum or other device, having a ratchetwheel upon the end of its shaft, of weighted vertically-vibrating pawls, a reciprocating shaft, to which said pawls are hinged, a crank-shaft, and a pitm an connecting the crank and reciprocating shafts, as will be hereinafter more fully set forth.

In the annexed drawings, the letter A designates a strong upright frame, the side pieces of which are suitably braced together, and afford bearings in their upper portions to a crank-shaft, B, and at their lower portions to a second shaft, 0. This shaft has a large ear wheel, D, that engages a pinion, a, upon b a fly-wheel shaft, E, having its hearings in the frame A between the shafts B G. Shaft E, as its name implies, carries the flywheel I.

In illustrating my invention I have shown shaft 0 provided with a winding-drum, Gr; but it is clear that by means of suitable gearings or pulleys and belts it may be con nected to the operative parts of a pump, grinding-mill, or saw-mill, and used to equal advantage as with a drum.

The shaft 0 has upon one end, outside of the frame A, a saw-toothed gear or ratchet wheel, H, the function of which will be hereinafter fully set forth.

Irepresents an oblong metallic guide, secured rigidly to the frame A in any suitable manner, directly over the ratchet-wheel H. In this guide is arranged an endwise-mova ble bar, J, of corresponding form, and con nected by means of a pitman, K, to the arm I) of the crank-shaft.

The rotation of the latter consequently im parts a vertically-reciprocating motion to the said bar J, that carries on its lower extremity the pawls L L. These pawls are hinged to the metallic cheek-plates c c, bolted or other wise secured to the lower end of the plungerbar, the former extending below the latter, as shown in Fig. l.

Pawl L is hinged to the cheek-plate o, and its free end bites upon the ratchet H during the descent of the plunger bar aforesaid; but during its ascent it slides over its teeth, and the pawl L bites upon it. One of these pawls is always at work, their operation being alternate; consequently the drum will receive a practically continuous motion, and the dead-centers be practically overcome. These pawls are each provided with a weight, 'w, outside of their pivotal points, that holds their free or griping ends constantly in contact with said ratchet-wheel, and renders their engagement therewith nearly instantaneous. Sometimes, instead of the pawls L L, I may use rack-bars R, hinged to the cheek-plates, like the said pawls, and provided'with re engaging weights.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the driving-shaft of a mill, hoisting-machine, or' other mech anism, and a ratchet-wheel on one end there of, of a reciprocating plunger-bar, pawls on the end of said bar alternately engaging said ratchet-wheel,aerank-shaft,andapitman conman, and crank-shaft, substantially as set necting said shaft and bar, substantially as forth.

specified. In testimony that I claim the above I have 2. The combination, with the driving-shaft hereunto subscribed my name in the presence 0, having a ratchet-wheel, H, of the reeipof two witnesses.
